INTERCHANGEABLE JEWEL MOUNTING.

Original application filed October 27,. 1825, Serial No. 65,082. Divided and this application filed July 12, 1927. Serial No. 205,173.

The present invention relates to jewelry and more particularly to aninterchangeable jewel mounting for mounting diil'erent stones or other ornaments.

My invention has for its object to provide an improved jewel mounting which is of simple construction and which may readily be operated without the use of tools to permit the removal of one jewel from the mounting and the substitution of another therefor.

The present invention is a: division of my oo-pcnding application, Serial No. 65,082,

filed October 27, 1925.

A specific object of the present invention is to provide aninterchangeable jewel mounting for rings which will accommodate stones of considerable depth. r I It is customary to set a stone in a plate or top (as it is called in the trade) which is soldered or otherwise secured to the ring. It is a specific object of the present invention to provide sliding engagement between a top and the head of a ring, the head'being notched to clear the lower point or part of the stone which projects below the bottom face of the top, and the notch being closed by a latch which holds the top in place.

My invention is applicable to other forms of jewelry as well as to rings, to permit interchanging of stones or. other ornaments whenever desired as for instance, to match various costumes or dresses.

With the above stated objects in View and other objects which will appear hereinafter, my invention consists in various novel features of construction and arrangements of parts as will be described in connection with the accompanying drawings illustrating a preferred embodiment of my invention, and

the novelty and scope of my invention will be defined in the appended claims.

In the accompanying drawings,

Fig. 1 is a side elevation of a ring provided with my improved interchangeable jewel mounting;

Fig. 2 is a similar View with the jewel and to removed;

ig. 3 is a fragmental, cross-sectional view taken on the line 33 of Fig. 1;

Fig. 4 is a bottom plan View of the top with a jewel set therein, and

Fig. 5 is a bottom plan view of an alternative form of jewel mounting.

In the drawings I have shown a. finger ring 10 formed with a hollow head. 11 of rectangularcross-section. In one of the side walls of this head a notch 12 is formed which is deep enough to clear the point'of a jewel, as

will be explained presently. The notch'as shown is V-shaped, but obviously it should conform to the profile of the lower portion of the jewel. Formed in the upper end walls of the hollow head 11 are a pair of undercut guides 13 which extend the full width of the head parallel to the axis of the ring. These guides are adapted to engage opposite bevelled edges 14 of a top 15 which is thus adapted to slide in a direction parallel to the axis of the ring. The top 15 is providedwith a central opening in which is set, a diamond or other jewel 13. To latch the top 15 in the head 11 I provide a spring 16 which at one end is secured to the under face of the top 15. The spring 16 is bent around the depending portion of the jewel as shown in Fig. 4 and its free end is bent downward and outward to fit into the point of the V-shaped notch 12. The head 11 is provided with a depression or socket 17 at the point of the notch to receive a depending lug 18 formed on the free end of the spring 16. Secured to the free end of the spring 16 is a plate 19 which is of such form as to fit snugly into and close the notch 12. The upper end of the plate 19 passes through a notch 20 formed in the top 15. The outer face of the plate 19 lies flush with the outer face of head 11 and the edge of the top 15 so that there will be no conspicuous evidence of the presence of a. catch. Obviously the head and top may be engraved with a suitable design to conceal all joints.

In operation the top 15 is slid into head 11 and then is locked in lug 18 to snap into the socket 17. Whenever it is desired to remove the jewel and substitute another the latch may be released by pressing the plate 19 upward to flex the spring 16 and lift the lug 18 out of the socket 17. The top 15 with its jewel 13 may then be slid out of engagement with the head 11 and another jewel and top be substituted therefor.

The modification shown in Fig. 5 differs from the construction described above merely in the fact thatthe spring 16 has a ringshaped portion 16 through which the lower end of the stone projects. By thus having the spring pass on either side of the stone instead of on one side only I overcome any place by permitting the,

tendency for the plate 19 to be skewed out of normal position when it is operated to flex the spring.

Having-thus described my invention and with the understanding that various slight changes of construction and arrangements of parts can be made without departing from V the spirit and scope-of my invention, I claim 1. An iutercliangeable jewel mounting comprising a base formed with side and end walls, a plate, means on the plate and the end walls cooperating to cltect sliding engagement of the plate with the base,a jewel set in the plate and projecting therethrough, one of the side walls being it'orn'ied with a notch to clear the projecting part of toe jewel, and a latch tor securing the plate to the base, said latch including a member fitting the notch when the latch is in latched position.

2. An interchangeable jewel inoiinting comprisinga base termed with side and end alls, a plate, the end walls being formed with ways to engage opposite edges oi? the plate, a jewel set in the plate and ha ring a point projecting through the plate, one of the side walls being termed with a notch to clear the pointof the jewel, and a latch for securing the'plate to the base, said latch inclueing a member fitting the notch when the latch is in closed position.

3. An interchangeable jewel mounting comprising base. formed with side and end walls, a plate, the end walls being formed with ways to engage opposite edges of the plate, a jewel in the plate and having a point projecting through the plate, one of the side walls being formed with a notch to clear the point of the jewel, a spring secured at one end to the plate, a lug at the other end of the spring, the base being formed with a socket to recelve the lug, and a member secured to the tree end of the spring and adapted to fit the notch when the lug is seated in the socket. j

4. An interchangeable jewel mounting comprising a base tormedwith side and end walls, the end walls being formed with ways to engage opposite edges of the plate, a plate slidable in said ways, a jewel set in the plate the ethrough,

one ot the side walls being V-shaped notch to clear the point of the ewel,

a spring secured at one'end to the inner face 0 t the plate and formed at the other end with a lug, the base being termed with a so llet in the point of the notch to receive the log, and a member secured to the tree end of the spring and adapted to lit the notch when the leg is seated in the socket with the outer face of said member lying flush with the outer face or the wall in which the notch is formed.

5. An interchangcable ewel mounting comprising a base formed with side and end walls, the end walls being termed with ways, a plate slidable in said ways, a jewel set in the plate and having a point projectingtherethrough, one ot the side wallsbeing formed with a notch to clear the point of the ewel, the plate being formed with a recess in one edge adapted to register with the notch when the plate is in normal position on the base, and a latch securing the plate tothe base, said latch including a member fitting the notch and the recess when the latch is in closed position.

6. An intcrchan gcable ewel mounting comprising a base formed with side and end walls, the end walls being formed with ways a plate slid-able in said ways, a jewel set in the plate and'having-a point projecting therethrougln one of the side walls being formed with a notch toclear' the point'et the jewel and with a socket in the bottom ofthe notch, a spring secured at one end to the inner face of the plate, the spring being formed at the opposite end witha lug 'engaging the socket when the plate is in normal position on the base, thespring being also termed with an intermediate annular portion through which the jewel projects, and a member secured to the'tree end of the spring and adapted to fit the notch when the lug is seated in the socket.
